Jackie, who describes her style as "classical crossover" (think Sarah Brightman) began singing at the age of seven after hearing music from "The Phantom of the Opera."

"AGT" judge Howie Mandel said it best when he proclaimed to an emotional Jackie following her explosive performance, "This is your moment, and you are the star!"

No word yet on what's next for Jackie as results from Tuesday night's show — and who gets through to the next round won't be revealed until Wednesday's results show. Jackie's website, however, notes she will perform at Carnegie Hall on Dec. 2, 2010.
